Henry,
Read the Perl documentation for more background on ithreads. ('perldoc
perlthrtut').
One solution could be to declare a global Thread::Queue. The worker threads
would input data into the queue and the parent thread would pull data
records out of the queue and write it to a file. The worker threads will
need a locking mechanism around the queue insert part. This solution is
likely only viable when the worker threads are doing a limited amount of
inserts into the queue.
